“…There are considerable achievements in the research of the space manipulator [1,2,3,4,5,6,7,8,9,10,11,12]. Many control methods have been proposed, such as PID control, robust control [13,14,15], adaptive control [16,17,18], fuzzy control, neural network control, and many hybrid control methods [19,20,21,22,23,24,25,26].…”
